Dagang Holding Group Co.,Ltd. (SZSE:300103) shares have continued their recent momentum with a 40% gain in the last month alone. Looking further back, the 12% rise over the last twelve months isn't too bad notwithstanding the strength over the last 30 days.

Since its price has surged higher, when almost half of the companies in China's Machinery industry have price-to-sales ratios (or "P/S") below 2.8x, you may consider Dagang Holding GroupLtd as a stock not worth researching with its 9.7x P/S ratio. However, the P/S might be quite high for a reason and it requires further investigation to determine if it's justified.

How Dagang Holding GroupLtd Has Been Performing

As an illustration, revenue has deteriorated at Dagang Holding GroupLtd over the last year, which is not ideal at all. One possibility is that the P/S is high because investors think the company will still do enough to outperform the broader industry in the near future. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Is There Enough Revenue Growth Forecasted For Dagang Holding GroupLtd?

Dagang Holding GroupLtd's P/S ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the industry.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 32%. As a result, revenue from three years ago have also fallen 79% overall. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenue over that time.

In contrast to the company, the rest of the industry is expected to grow by 23% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

In light of this, it's alarming that Dagang Holding GroupLtd's P/S sits above the majority of other companies. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent revenue trends is likely to weigh heavily on the share price eventually.

The Bottom Line On Dagang Holding GroupLtd's P/S

Shares in Dagang Holding GroupLtd have seen a strong upwards swing lately, which has really helped boost its P/S figure. Using the price-to-sales ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

Our examination of Dagang Holding GroupLtd revealed its shrinking revenue over the medium-term isn't resulting in a P/S as low as we expected, given the industry is set to grow. When we see revenue heading backwards and underperforming the industry forecasts, we feel the possibility of the share price declining is very real, bringing the P/S back into the realm of reasonability. Should recent medium-term revenue trends persist, it would pose a significant risk to existing shareholders' investments and prospective investors will have a hard time accepting the current value of the stock.
